Radiation Therapy Fundamentals
- LINAC (Linear Accelerator): Most common RT machine in GCC; uses photon (X-ray) or electron beams
- Photon beams: Deep-penetrating; used for most solid tumours (breast, lung, prostate, H&N)
- Electron beams: Superficial only — skin lesions, post-mastectomy chest wall
- IMRT: Intensity-modulated RT — shapes dose around organs at risk; standard for H&N and prostate
- IGRT: Image-guided RT — daily imaging before each fraction to verify position
- VMAT: Volumetric arc therapy — IMRT delivered as rotating arc; faster treatment
- SRS (Stereotactic Radiosurgery): Single high-dose fraction for brain metastases or AVMs; Gamma Knife, CyberKnife
- SBRT/SABR: Stereotactic body RT — 3–5 very high-dose fractions; lung, liver, spine, prostate oligomets
- Gamma Knife: Dedicated intracranial SRS unit; uses cobalt-60 sources in a helmet
- CyberKnife: Robotic LINAC — can treat any body site with real-time tumour tracking
- Nursing: Patients often have frames/immobilisation devices; monitor neurological status; short admission
| Schedule | Dose/Fraction | Duration | Use |
|---|---|---|---|
| Conventional | 1.8–2.0 Gy/fx | 5–7 weeks | H&N, breast, gynaecological |
| Moderate Hypo | 2.4–3.4 Gy/fx | 3–4 weeks | Breast (15–16 fx standard) |
| Ultra Hypo | 5–7.25 Gy/fx | 1–2 weeks | Prostate, palliative |
| SBRT | 6–20 Gy/fx | 1–2 weeks (3–5 fx) | Lung, liver, oligomets |
| SRS | 12–24 Gy | Single fraction | Brain mets, AVM, trigeminal |
- Gray (Gy): Unit of absorbed dose = 1 Joule of energy absorbed per kilogram of tissue
- Centigray (cGy): 1/100 of a Gray; 200 cGy = 2 Gy (one conventional fraction)
- Sievert (Sv): Biological effective dose — accounts for radiation type; used in radiation protection
- millisievert (mSv): For occupational & public dose limits; annual limit staff = 20 mSv
- Dose prescription: e.g. 60 Gy in 30 fractions = 2 Gy per fraction over 6 weeks
Patient positioned in treatment position; immobilisation device made (shell/mask for H&N, breast board); tattoo marks placed. Nurse role: explain procedure, manage anxiety, IV contrast if needed.
Radiation oncologist delineates GTV (Gross Tumour Volume), CTV (Clinical Target Volume including microscopic spread), PTV (Planning Target Volume — CTV + margin for setup uncertainty).
Medical physicist and dosimetrist design beam arrangement to deliver prescribed dose to PTV while respecting dose constraints for organs at risk (OARs) — e.g. spinal cord max dose, lung V20.
Radiation oncologist approves plan; physicist performs quality assurance checks. Nurse attends MDT planning meetings where appropriate.
RTT delivers treatment (nurse NOT present in bunker during beam-on). Nurse reviews patient before/after fractions — assess symptoms, manage side effects, provide support.
Radiation Oncologist
Prescribes treatment, contours target volumes, approves plans, manages medical aspects of care.
Medical Physicist
Ensures accuracy of dose delivery, designs treatment plans, performs QA, maintains equipment safety.
Radiation Therapist (RTT)
Operates LINAC, positions patient, delivers each fraction. This is NOT the nurse role.
Dosimetrist
Creates treatment plans using planning software under physicist supervision.
Radiation Nurse
Assessment, patient education, side effect management, symptom control, emotional support, care coordination.
Radiation Safety Officer
Ensures departmental compliance with radiation protection regulations (UAE FANR / Saudi NRRC).
- Bragg Peak: Protons deposit maximum dose at a precise depth then stop — sparing tissue beyond tumour
- Advantage over photons: Less exit dose — ideal for paediatric tumours, skull base, spinal cord tumours
- GCC availability: Select centres investing in proton facilities; growing availability across region
- Nursing: Same side effect profile as photon RT but potentially reduced late toxicity; nursing care is similar
- Internal radiation: Radioactive source placed inside or adjacent to tumour
- HDR brachytherapy: High dose rate — Iridium-192; remote afterloader; patient NOT radioactive between fractions
- LDR brachytherapy: Low dose rate — patient IS radioactive; radiation precautions required
- Seeds (permanent): Iodine-125 seeds for prostate — patient goes home radioactive
- Applications: Cervical, endometrial, prostate, breast, skin, oesophageal cancers
Common Treatment Sites & Side Effects
Mucositis — Most Debilitating Acute Toxicity
- Onset: Week 2–3 of RT; peaks weeks 4–5; heals 4–6 weeks post-RT
- Grade 1: Asymptomatic/mild — oral hygiene, frequent rinsing (saline/bicarb)
- Grade 2: Moderate pain, soft diet — topical analgesics, nutritional support
- Grade 3: Severe pain, unable to eat — IV analgesia (opioids), PEG feeding, hospitalisation
- Grade 4: Life-threatening — intensive care, TPN consideration
- PEG timing: Prophylactic gastrostomy (PEG) often inserted before RT in high-risk H&N; nurse key in education, care and monitoring
Xerostomia (Dry Mouth)
- Salivary gland irradiation → permanent hyposalivation if not spared
- Prevention: IMRT sparing of parotid glands (constraint: mean dose <26 Gy)
- Management: Artificial saliva sprays, sugar-free gum, pilocarpine (cholinergic stimulant — assess contraindications), frequent sips of water
- Dental review BEFORE RT: Extractions must be done before RT — post-RT extractions risk osteoradionecrosis
Other H&N Toxicities
- Radiation dermatitis: Skin in radiation field — grade using RTOG/CTCAE; moist desquamation common in neck folds
- Dysphagia: Swallowing difficulty — SLT review, modified texture diet, PEG if severe; monitor aspiration risk
- Trismus: Jaw fibrosis — jaw-opening exercises START during RT to prevent; sticks/TheraBite device
- Hypothyroidism: Late effect if thyroid in field — TSH monitoring at 6, 12 months post-RT and annually
- Osteoradionecrosis (ONR): Late, rare but serious — jaw bone necrosis; risk factors include dental extraction post-RT, high dose, poor oral hygiene
- Hearing loss: If cochlea in field; audiometry monitoring
- Skin reaction: Most common acute toxicity; erythema (Grade 1) → dry desquamation (Grade 2) → moist desquamation (Grade 3) in skin folds; Grade 4 = ulceration (rare)
- Fatigue: Universal; peaks in final weeks; discuss energy conservation, gentle exercise (evidence-based)
- Lymphoedema: Risk after axillary RT ± axillary dissection; nurse education on precautions (no BP in affected arm, avoid cuts, skin hygiene)
- Pneumonitis: Risk 4–12 weeks post-RT if lung volume irradiated; monitor for cough, dyspnoea, fever; CXR/CT if suspected
- Cardiac late effects: Left-sided breast RT — deep inspiration breath-hold (DIBH) technique reduces cardiac dose; nurse explains technique
- Body image: Psychological support; assess emotional wellbeing; refer breast care nurse/psychologist
- Radiation pneumonitis: Onset 4–12 weeks post-RT; symptoms: cough, progressive dyspnoea, fever, pleuritic chest pain; Grade ≥2 requires oral prednisolone (40–60 mg tapered over 6 weeks)
- Oesophagitis: Onset week 2–3 during RT; dysphagia, odynophagia; soft diet, liquid analgesics, mucaine/viscous lignocaine; Grade 3 may need NGT/PEG
- Fatigue: Often compounded by underlying disease and systemic treatment
- Skin reaction: Usually mild for lung RT — monitor entry/exit beam sites
- Haemoptysis: May be tumour-related or RT reaction — assess quantity; escalate if significant
- Pulmonary fibrosis: Late effect at 6–24 months; progressive breathlessness; refer respiratory team
- Radiation proctitis (acute): Diarrhoea, urgency, tenesmus, rectal bleeding; onset week 3–4; low-residue diet, loperamide, antispasmodics, rectal steroid foam
- Radiation cystitis (acute): Dysuria, frequency, urgency, haematuria; hydration ↑ 2–3L/day; alpha-blocker (tamsulosin), exclude UTI
- Vaginal effects: Vaginal dryness, stenosis (cervix/endometrial RT) — vaginal dilators START 4–6 weeks post-RT; water-based lubricants; sensitive patient education
- Sexual dysfunction: Erectile dysfunction (prostate RT), dyspareunia, libido — counsel patient and partner; referral to sexual health if needed
- Lymphoedema: Post-pelvic RT + node dissection — bilateral leg/genital lymphoedema; compression, skin care
- Late effects: Fistula (rare), bowel stricture, rectal bleeding (chronic proctitis); refer GI/urology as appropriate
- Fatigue: Most common; profound during and after WBRT (whole brain RT); counsel on activity pacing
- Alopecia: Within the radiation field only (not universal as with chemotherapy); partial or complete depending on field; may be permanent with high dose
- Nausea/vomiting: Especially WBRT; prescribe prophylactic antiemetic (dexamethasone reduces cerebral oedema and nausea)
- Somnolence syndrome: Onset 6–8 weeks post-RT; extreme sleepiness, lethargy, low-grade fever; self-limiting (2–4 weeks); reassure patient and family
- Cognitive effects: Concentration, memory — more marked with WBRT vs. SRS/focal RT; memantine considered in WBRT
- Radiation necrosis: Late effect months–years post-RT; focal neurological deficits; MRI vs PET to distinguish from tumour recurrence; bevacizumab if severe
| Grade | General Description | Intervention Level | Example — Dermatitis |
|---|---|---|---|
| Grade 1 | Mild; asymptomatic or minimal symptoms; no intervention indicated | Patient education, monitoring, topical | Faint erythema, dry desquamation |
| Grade 2 | Moderate; minimal intervention; limits instrumental ADLs | Medication, dietitian/SLT referral | Moderate erythema, patchy moist desquamation in folds |
| Grade 3 | Severe; medically significant; limits self-care ADLs; hospitalisation may be indicated | IV medications, treatment break consideration | Moist desquamation outside folds, bleeding from minor trauma |
| Grade 4 | Life-threatening; urgent intervention indicated | Urgent medical/surgical intervention; likely RT pause | Skin necrosis, full-thickness dermal loss; spontaneous bleeding |
| Grade 5 | Death related to adverse event | — | Death from complications |
Radiation Skin Care Protocol
- Gentle washing: Mild, unscented soap (Dove unscented); lukewarm water; gentle pat dry with soft cloth — do NOT rub
- Moisturisers: Apply aqueous cream, Calendula cream, or prescribed barrier cream twice daily; apply AWAY from field markings
- Clothing: Loose-fitting, soft cotton clothing over treated area; avoid underwired bras during breast RT
- Shaving: Electric razor only within treatment field if necessary; ideally avoid shaving treated skin
- Deodorant: Aluminium-free deodorant for axilla/breast treatments; some centres advise none in field during RT
- Heat: No hot water bottles, heat pads, or saunas over treated area
- Swimming pools: Chlorinated water irritates irradiated skin — avoid during RT course and until healed
- Jacuzzi/spa: Heat, chemicals, and jets — contraindicated during RT
- Sun exposure: Irradiated skin remains hypersensitive to UV for at least 1 year post-RT — SPF 50+ sunscreen, protective clothing
- Perfumes/fragrances: Alcohol-based products can dry and irritate treated skin
- Tape: Medical tape directly on irradiated skin can cause trauma on removal
- Scratching: Counsel patient to pat rather than scratch pruritic areas; antihistamine if severe itch
| RTOG Grade | Clinical Description | Nursing Intervention | Products |
|---|---|---|---|
| Grade 1 | Faint erythema, dry desquamation, decreased sweating | Moisturise, education, monitor | Aqueous cream, Calendula, Miaderm |
| Grade 2 | Moderate/brisk erythema, patchy moist desquamation in skin folds | Barrier cream, loose dressings if oozing, analgesia | Flamazine (silver sulfadiazine), Mepitel One |
| Grade 3 | Confluent moist desquamation, pitting oedema, outside skin folds | Non-adherent wound dressings, tissue-type assessment, analgesia, consider RT break | Mepilex Lite, Mepitel, Allevyn Thin |
| Grade 4 | Ulceration, haemorrhage, necrosis | Urgent wound care, plastic surgery review, RT pause, pain management | Specialist wound products; tissue viability nurse |
- Permanent tattoos: Small (1–2 mm) ink dots made at simulation — permanent; patient MUST NOT attempt to remove; explain purpose
- Temporary ink marks: Some departments use temporary skin markers for setup; patient must not wash these off; report if marks become faint
- Why markers matter: Ensure identical patient positioning each fraction — treatment accuracy depends on reproducible alignment
- Faded marks: Instruct patient to inform RTT immediately if marks fade — do NOT redraw without RTT confirmation
- Cultural sensitivity: Some GCC patients may have concerns about permanent tattoos (Islamic perspective); discuss with clinical team — alternative methods available in some centres
- What is bolus? Tissue-equivalent material (wax, aquaplast) placed on skin surface before each fraction
- Purpose: Deliberately increases skin dose — used when tumour is superficial (post-mastectomy chest wall, skin tumours, scalp)
- Effect on skin: Significantly increases skin reaction severity — anticipate and manage more aggressively
- Nurse role: Be aware when bolus is part of the plan; explain to patient why skin reaction will be more significant; increase frequency of skin assessment
- RTT applies bolus: Nurses do not apply bolus — this is an RTT function during treatment delivery
Before Treatment Starts
- Explain what radiation dermatitis is and when to expect it
- Provide written skin care leaflet (Arabic and English)
- Discuss appropriate clothing
- Ensure adequate moisturisers supplied
During Treatment
- Assess skin at weekly review appointment
- Grade and document reaction
- Escalate if Grade 3 — consider RT break discussion
- Reinforce what to avoid; update advice as reaction evolves
After Treatment
- Skin continues to react for 1–2 weeks post-RT
- Continue moisturising until fully healed
- Sun protection for 1 year minimum
- Follow-up if skin does not heal in 4–6 weeks
Brachytherapy Nursing
- Source: Iridium-192 (Ir-192); high activity source on a cable in remote afterloading machine
- Remote afterloading: Source travels from machine through tubes/catheters to patient; ALL staff leave room during treatment (minutes only)
- Between fractions: Source is back in the machine — patient has NO radioactive material; nurse can provide full care without any special precautions
- Typical sites: Cervix, vagina, endometrium, prostate, breast, skin, lung, oesophagus
- Duration per fraction: Minutes (typically 10–20 minutes of actual beam-on time)
- Nursing care: Pain management (applicators can be uncomfortable), catheter care, anxiety support, IV access, vital signs
- Sources: Caesium-137 (Cs-137) wires/pellets; or Iodine-125 (I-125) seeds (permanent prostate implants)
- Patient IS radioactive: Sources remain in or near patient for extended period (hours to days) or permanently (seeds)
- Radiation protection principles — Time, Distance, Shielding:
- Time: Minimise time spent close to patient; prioritise care tasks; prepare everything before entering room
- Distance: Inverse square law — doubling distance reduces dose to quarter; stand at foot of bed where possible; lead shield at bedside
- Shielding: Lead apron/shield between nurse and source; portable lead screens at bedside
TIME
- Plan all care before entering room
- Gather all equipment outside room first
- Rotate nurses to distribute dose exposure
- Keep total time near patient as brief as possible
DISTANCE
- Inverse square law: 2x distance = ¼ dose
- Use extended IV tubing where possible
- Stand at foot/side of bed, not directly beside source
- Use bedside lead screen when stationary
SHIELDING
- Lead apron for gynaecological sources
- Portable lead screens at bedside
- Lead-lined room walls provide structural shielding
- Wear personal dosimetry badge (TLD/OSL)
- Procedure: Transrectal ultrasound-guided implant of 60–120 I-125 seeds into prostate; day-case or overnight procedure
- Patient goes home radioactive: Seeds emit low-energy radiation; activity decays over ~1 year (half-life 60 days)
- Patient discharge education (critical):
- Avoid prolonged close contact with pregnant women for first 2 months
- Keep children (under 10) at arm's length for extended periods for first 2 months
- Can sleep in same bed as adult partner after the first few weeks
- Urinary symptoms (frequency, urgency, hesitancy) common first few weeks — alpha-blocker medication
- Seed loss: Small risk of passing seed in urine — instruct to urinate through strainer for first 2 weeks; provide sharps container for seed disposal
Cervical and endometrial cancers — most common brachytherapy site requiring inpatient nursing care.
- Types: Intracavitary (ring and tandem, ovoids) for cervical cancer; vaginal cylinder for endometrial
- HDR procedure nursing: Patient in theatre for applicator insertion under GA/sedation; post-procedure vital signs, pain assessment, catheter care, urinary monitoring
- LDR inpatient stay: Caesium sources in situ 20–40+ hours; bed rest with catheter; full radiation precautions; bowel preparation to prevent displacement
- Pain management: Applicators can cause significant pelvic pain — regular analgesia, reassess frequently
- Vaginal packing: Gauze packing maintains applicator position; nurse checks packing has not displaced; report any bleeding
- Post-procedure: Applicator removal (often in ward by medical team); vaginal bleeding/discharge expected; discharge care and vaginal dilator education
- Cultural sensitivity: Pelvic examinations and vaginal procedures — ensure privacy, same-gender staff where possible, clear explanation
Step 1 — Do Not Touch
Never pick up or handle a dislodged source with bare hands. Maximise distance immediately.
Step 2 — Use Long Forceps
Long-handled forceps and lead-lined container are kept in brachytherapy rooms. Use these to place dislodged source in the container.
Step 3 — Alert Immediately
Inform radiation oncologist, medical physicist, and Radiation Safety Officer immediately. Complete incident report.
Systemic & Concurrent Treatments
Clinical Applications
- Head & neck cancer: Weekly cisplatin 40 mg/m² or 3-weekly 100 mg/m² with definitive RT
- Cervical cancer: Weekly cisplatin 40 mg/m² with pelvic RT ± brachytherapy boost
- Lung (stage III): Concurrent platin-based doublet with thoracic RT
- Anal canal / rectal: Cisplatin + 5-FU or capecitabine + pelvic RT
Toxicity Enhancement with Concurrent RT
- Mucositis: Worse grade and longer duration in H&N concurrent
- Nausea/vomiting: Cisplatin = highly emetogenic; 5-HT3 antagonist + dexamethasone + NK1 receptor antagonist
- Myelosuppression: Monitor FBC weekly; hold cisplatin if ANC <1.5 or platelets <100
- Skin: More severe radiation dermatitis with concurrent
Cisplatin Toxicities — Nurse Monitoring
- Nephrotoxicity (most important): Monitor creatinine/eGFR before EACH cycle; ensure pre-hydration (1–2L IV saline before cisplatin, IV fluids after); ensure adequate urine output >100 mL/hr during infusion; hold if creatinine rises >25% from baseline
- Ototoxicity: High-frequency hearing loss (irreversible); audiometry if ≥3 cycles; report new tinnitus or hearing change
- Peripheral neuropathy: Tingling, numbness in hands/feet; cumulative; assess before each cycle
- Electrolyte loss: Magnesium, potassium wasting — monitor and replace; hypomagnesaemia causes muscle cramps, tremor
- Use: Head & neck squamous cell carcinoma — alternative to cisplatin (bioradiotherapy)
- Acneiform rash: Characteristic pustular rash on face, scalp, chest, back; grade 1–4; paradoxically associated with better tumour response; moisturise, topical/systemic antibiotics (doxycycline) if Grade ≥2
- Infusion reactions: Risk at first infusion — premedicate with antihistamine + corticosteroid; observe during infusion; Grade 3–4 = stop infusion immediately, manage anaphylaxis protocol
- Combined skin toxicity: Cetuximab rash + radiation dermatitis in same fields — complex skin management required
- Electrolytes: Hypomagnesaemia common — monitor and replace
- Abscopal effect: RT may enhance systemic immune response to immunotherapy — irradiated tumour acts as in-situ vaccine; being studied in clinical trials
- Agents used: PD-1/PD-L1 inhibitors (pembrolizumab, nivolumab, durvalumab) with RT in lung, H&N, bladder, oesophageal cancers
- Immune-related adverse events (irAEs): Pneumonitis, colitis, hepatitis, thyroiditis, dermatitis, myocarditis — can occur during or after RT; may be difficult to distinguish from radiation toxicity (pneumonitis)
- Pneumonitis differential: Radiation pneumonitis vs immunotherapy pneumonitis vs combined — clinical/radiological assessment; treatment = steroids in both cases but inform oncologist immediately
- Nurse education: Educate patients about immune toxicity symptoms — breathlessness, diarrhoea, rash, jaundice; when to call urgently
- Androgen deprivation therapy (ADT): LHRH agonists (goserelin, leuprolide) ± anti-androgens given before, during, and after RT for intermediate/high-risk prostate cancer
- Duration: Short-term (6 months) for intermediate-risk; long-term (2–3 years) for high-risk; combined with RT shown to improve survival
- Nurse role — ADT side effects:
- Hot flushes: Common and distressing; lifestyle advice (cool environment, layers), venlafaxine, cyproterone for refractory cases
- Bone health: ADT reduces bone density — baseline DEXA scan, calcium/vitamin D supplements, bisphosphonates if indicated; fracture risk assessment
- Mood/cognitive effects: Depression, memory changes, fatigue — psychological screening, refer if needed
- Metabolic syndrome: Weight gain, glucose intolerance — lifestyle advice, monitor blood sugar
- Sexual function: Erectile dysfunction, loss of libido — counsel patient and partner; referral if needed
Steroids are frequently used in radiation oncology for acute toxicity management.
- Dexamethasone — brain RT: Reduces cerebral oedema; 4–16 mg/day during brain RT or for raised ICP; taper after RT; monitor blood glucose (steroid-induced hyperglycaemia common)
- Prednisolone — radiation pneumonitis: Grade ≥2 pneumonitis; 40–60 mg/day tapered over 6–12 weeks; DO NOT stop abruptly
- Nurse monitoring on steroids: Blood glucose (daily initially), mood changes (insomnia, euphoria, psychosis), GI symptoms (prescribe PPI), blood pressure, infection risk, Cushingoid features
- PCP prophylaxis: Cotrimoxazole for patients on prolonged high-dose steroids (risk of Pneumocystis pneumonia)
- Steroid card: Ensure patients on prolonged steroids carry a steroid card; do not stop without medical instruction
